Module fermium::sensor

Lets SDL use various sensors (such as the accelerometer in a phone).

SDL_Init must have been called with the SDL_INIT_SENSOR flag. This causes SDL to scan the system for sensors, and load appropriate drivers.

Structs

SDL_Sensor

SDL’s opaque sensor type.

SDL_SensorID

This is a unique ID for a sensor for the time it is connected to the system.

SDL_SensorType

The different sensors defined by SDL

Constants

SDL_SENSOR_ACCEL

Accelerometer

SDL_SENSOR_GYRO

Gyroscope

SDL_SENSOR_INVALID

Returned for an invalid sensor

SDL_SENSOR_UNKNOWN

Unknown sensor type

SDL_STANDARD_GRAVITY

Accelerometer sensor
